Aquatic Moss (Fontinalis spp.)
Updated: Jun 23
Aquatic moss (aka water moss) is a dark green plant that attaches to submerged rocks or logs. The stems branch and are entirely covered by tiny, sharply pointed, ridged leaves (see Maria's photos below).
These are not true vascular plants and they reproduce by stolons, plant fragments, or spores rather than by flowers and seeds. Aquatic moss provides habitat for aquatic insects, larvae, and other microorganisms. Small fish species will nest in it. To date it has only been identified in Zone 7 of Conway Lake by Maria Gross - keep an eye out for it elsewhere on the lake.
